LeetCode:Kth Largest Element in an Array(need update)

problem:

Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element.

For example,
Given [3,2,1,5,6,4] and k = 2, return 5.

Note:
You may assume k is always valid, 1 ≤ k ≤ array's length.

class Solution {
public:
    int findKthLargest(vector<int>& nums, int k) {
        sort(nums.begin(),nums.end());
        return nums[nums.size()-k];
    }
};
